Detailed Description
The invention will be further described with reference to the following specific examples,
as shown in fig. 1, the technical scheme of the invention specifically refers to an automatic production device capable of reducing the workload of operators and effectively improving the production efficiency and quality of rubber products, and for the operators, the function of the automatic production device is only to control the normal operation of the machine. When the device is used for processing rubber products, an operator places rubber materials into the rubber extruder 2, the device starts automatic operation, the rubber materials enter the rubber extruder 2 and are extruded from the discharge outlet 28 to form rubber belts, the rubber belts are driven forward by the transfer cutting device 3 and are subjected to calendaring in the transfer cutting device 3, the transfer cutting device 3 cuts the calendared rubber belts into sections of rubber belts, and the cut rubber belts are transferred onto the conveyor belt 4. The conveyor belt 4 conveys the rubber belt located on the conveyor belt forward, the rubber belt is conveyed to the die of the vulcanizing machine 6 by the manipulator 5, the vulcanizing machine 6 carries out die pressing vulcanization on the rubber belt in the die, finally the manipulator 5 conveys the rubber product subjected to die pressing vulcanization to the centrifugal screening device 7, and it is emphasized that in the device, the manipulator 5 also simultaneously processes the rubber belt on the conveyor belt 4 and conveys the rubber product subjected to die pressing vulcanization to the centrifugal screening device 7 at the same time when the rubber belt on the conveyor belt 4 is conveyed to the die of the vulcanizing machine 6, and the two links are synchronous, so that the efficiency can be greatly improved, feeding is carried out after the completion of the blanking, and the feeding is carried out in the device. Finally, the rubber products subjected to compression molding and vulcanization fall into a centrifugal screening device 7, are scattered into large materials, small materials and burrs, and are screened and separated finally.
As shown in fig. 2, fig. 2 shows the internal structure of the rubber extruder 2 and the working principle thereof, the rubber extruder 2 has the function of extruding the rubber material into a rubber belt through the rubber extrusion screw 26 and extruding the rubber belt from the discharge outlet 28, so that the rubber belt can be conveniently processed in the next link, in the conventional mode, the rubber extruder 2 is fed with two modes, namely cold feeding and hot feeding, and the rubber belt extruded from the discharge outlet 28 has lower temperature for cold feeding, so that the rubber belt is inconvenient to be cut into blocks in the follow-up process, and even the continuous cutting phenomenon can occur. For the hot feeding mode, the rubber material is firstly heated to a certain temperature outside and then is put into the feeding port 27 of the rubber extruder 2, and finally extruded, and although the hot feeding can solve the problem of easy cutting later, a great amount of time is wasted due to the preheating, so that the whole processing period is long, and the processing efficiency is reduced. Therefore, there is no optimal solution for either hot or cold feeding in the conventional feeding mode. In the technical scheme of the invention, the water flow channel 29 is added in the extruder cylinder 25, the water flow channel 29 is communicated with the external water tank 21, water in the water tank 21 is pumped into the water flow channel 29 by the water pump 24, and the water-saving type rubber extruder further comprises the heater 23, wherein the heater 23 directly heats the water in the water flow channel 29 or the water tank 21, so that the extruder cylinder 25 can keep a certain temperature, when a rubber material enters the extruder cylinder 25 at a lower temperature, the rubber material is gradually heated in the forward extrusion process of the rubber material by the rubber extrusion screw 26, and finally the rubber belt extruded from the exhaust port 28 of the rubber extruder 2 keeps a certain temperature, thereby achieving the purpose of cold feeding and hot discharging and facilitating the subsequent links. Also in this process, the heating and extrusion are kept synchronized, so that a lot of time can be saved.
Further, the water flow channel 29 is connected with the water temperature sensor 22, and when the water temperature is too high or too low, a feedback signal can be given to the heater 23, so that the heater 23 keeps intermittently working, the temperature of the extruder cylinder 25 is ensured, the extruded rubber belt has a constant temperature, and the situation that the temperature is too low or too high is avoided.
Further, as shown in fig. 2, the number of the discharge ports 28 of the rubber extruder 2 is at least one, and the plurality of discharge ports 28 can ensure that the rubber belt is discharged from the rubber extruder 2 with higher yield, so that more rubber belts are obtained, and the molding vulcanization of the subsequent links is facilitated.
As shown in fig. 3 and 4, after the rubber belt is extruded from the discharge port 28 of the rubber extruder 2, the rubber belt bypasses the static driving roller 312 and is wound on the movable driving roller 313, the pressing driving roller 315 presses the rubber belt positioned on the movable driving roller 313 under the action of the first lifting cylinder 316, the rubber belt is in a pressed state on the passive driving roller 313 and the pressing driving roller 315, and the rubber belt is slowly transferred out due to the rotation of the movable driving roller 313, when the rubber belt is transferred to the position of the cutting mechanism 32, the cutter continuously cuts off the rubber belt under the action of the second lifting cylinder 321, the sliding table 324 is installed on the first transfer cylinder 323 positioned on the installation frame 311, the sliding table 324 is in an L shape, the third lifting cylinder 325 is installed on the vertical surface of the sliding table 324, the sucking disc 326 on the piston rod of the third lifting cylinder 325 generates suction under the action of the external driving force, and sucks the rubber belt, at the moment, the first transfer cylinder 323 drives the piston rod 326 moves forward, and when the rubber belt is transferred to the position of the conveyor belt 4, the sucking disc 326 on the third lifting cylinder 325 drops the rubber belt onto the conveyor 4.
As shown in fig. 5 and 6, the manipulator 5 includes a first manipulator 53 and a second manipulator 54, the first manipulator 53 is used for sucking the rubber belt on the conveyor belt 4 and transferring the rubber belt to a mold of the vulcanizing machine, the first manipulator 53 moves along the linear guide rail 51 to a side close to the conveyor belt 4 firstly in the working process, the fourth lifting cylinder 531 moves downwards, the second transfer cylinder 532 can be adjusted according to the position of the rubber belt on the conveyor belt 4, the rubber belt on the conveyor belt 4 is sucked, and the second transfer cylinder 532 of the first manipulator 53 can be more matched with the movement condition because the conveyor belt 4 moves. Furthermore, on the basis that the fourth lifting cylinder 531 can move up and down, the first manipulator 53 may further add a lifting cylinder, and the working speed of the lifting cylinder is slightly slower than that of the fourth lifting cylinder 531, so that the situation that the fourth lifting cylinder 531 runs too fast to collide with the conveyor belt 4 can be avoided. The suction cup 534 on the first robot 53 sucks the rubber tape by suction generated by an external driving source like the suction cup 326 on the transfer cutting device 3. The second manipulator 54 is used for sucking and transferring the rubber product that is subjected to mold pressing and vulcanization on the vulcanizing machine 6 into the centrifugal screening device 7, when the slide carriage 52 is moved to a side close to the vulcanizing machine 6 on the linear guide rail 51, the fifth lifting cylinder 541 of the second manipulator 54 moves downwards, the rubber product on the mold is sucked by the suction cup 534, and likewise, the lifting cylinder can be further added on the basis of the fifth lifting cylinder 541, but since the position is fixed when the mold of the vulcanizing machine 6 is withdrawn, a transfer cylinder is not required, and meanwhile, the operating principle of the suction cup 534 is consistent with that of the suction cup 534 on the first manipulator 53.
As shown in fig. 7, the centrifugal screening apparatus 7 includes a rubber edge removing machine 71 and a screening mechanism 72, after the second manipulator 54 transfers the rubber product to the rubber edge removing machine 71, the rubber product mainly falls into a centrifugal cylinder 711, a second valve plate 715 is disposed on the centrifugal cylinder 711, initially, the rubber product falls onto the second valve plate 715, after the last rubber product in the centrifugal cylinder 711 completes edge removing, a first valve plate 713 mounted on the centrifugal cylinder 711 is opened under the control of a first opening and closing cylinder 714, so that the rubber product after edge removing is separated from the centrifugal cylinder 711 and enters the screening mechanism 72, then the first valve plate 713 is closed, and the second valve plate 715 is opened under the control of a second opening and closing cylinder 716, so that the rubber product falls into the centrifugal cylinder 711. In this way, excessive materials in the centrifugal cylinder 711 can be avoided, the edge disassembly efficiency of the centrifugal cylinder 711 is affected, and the processing links are tightly and orderly carried out. The rubber product leaving from the centrifugal cylinder 711 is disassembled into large material, small material and burr, and enters the screening mechanism 72, the screening mechanism 72 mainly consists of a screen plate 721 arranged from top to bottom, the screen plate 721 is provided with screen openings 722, the number of the screen openings 722 is uniformly distributed, a vibrator 723 is arranged below the screen plate 721, the material on the screen plate 721 continuously moves forwards, the screen opening 722 of the screen plate 721 positioned at the uppermost layer is the largest, the screen openings 722 are just arranged to prevent the burr from falling onto the screen plate 721 positioned at the lower layer, the large material and the small material fall onto the lower layer, the screen openings 722 on the screen plate 721 positioned below the uppermost layer just enable the small material to fall, the screen plate 721 positioned at the bottommost layer can not be provided with the screen openings 722, and the small material can not fall from the screen openings 722. In contrast, in the present embodiment, only three sizes of materials are mentioned, in practical application, the number of the sieve plates 721 will also be increased according to the types of the materials, and the sizes of the materials are not necessarily arranged in order of burrs, large materials, and small materials as described in the present embodiment. In practical applications, the arrangement is performed according to the actual size of the material.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
